Description
- This is a Continuation Application of PCT Application No. PCT/JP2009/054112, filed Feb. 26, 2009, which was published under PCT Article 21(2) in English.
- This application is based upon and claims the benefit of priority from prior Japanese Patent Application No. 2008-056760, filed Mar. 6, 2008, the entire contents of which are incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to a battery apparatus for use in a vehicle that is not subjected to forced draft.
- 2. Description of the Related Art
- It has been conventionally known that a plurality of batteries are accommodated in a battery box (see, e.g., JP-A 241700-1996 (KOKAI)).
- However, a battery apparatus disclosed in the literature of the conventional technology is not suitable for use in a light vehicle.
- For example, since a light vehicle does not include, e.g., a fan that performs forced draft, efficiently cooling the battery apparatus is difficult. When using the battery apparatus in a light vehicle, the battery apparatus is often exposed to outside air. Therefore, temperatures of a plurality of batteries cannot be uniformed. Accordingly, durabilities of the respective batteries are uneven.
- It is an object of the present invention to provide a battery apparatus suitable for use in a vehicle that is not subjected to forced draft.
- According to an aspect of the present invention, there is provided a battery apparatus mounted in a vehicle that is not subjected to forced draft, the battery apparatus comprising: a plurality of rectangular parallelepiped batteries stacked in a direction vertical to a traveling direction of the vehicle; a rectangular parallelepiped battery box that accommodates the plurality of rectangular parallelepiped batteries therein; and a heat equalizing plate that is brought into contact with the plurality of rectangular parallelepiped batteries.

-
FIG. 1 is a structural view showing a structure of a battery apparatus 1 according to a first embodiment of the present invention. It is to be noted that like reference numerals denote like parts throughout the drawings, and different parts will be mainly explained. Likewise, in the other embodiments, a repeated explanation will be omitted. - Here, in
FIG. 1 , in a state where the battery apparatus 1 is mounted in an electric light vehicle, an arrow direction of an axis Z is an upper direction, and an arrow direction of an axis Y is a traveling direction of the electric light vehicle. Further, an axis X, the axis Y, and the axis Z are axes 90 degrees apart, respectively. This can be likewise applied to the other drawings. - The electric light vehicle is a vehicle that is not subjected to forced draft. The electric light vehicle is, e.g., a bicycle. The battery apparatus 1 is mounted below, e.g., a saddle or a rear body of the bicycle. Therefore, the battery apparatus 1 is placed at an environmentally severe position where the battery apparatus 1 is exposed to outside air, for example.
- The battery apparatus 1 includes 10
batteries 2, abattery box 3 that accommodates the 10batteries 2, and aheat equalizing plate 10. - The
battery 2 has a substantially rectangular parallelepiped shape. In regard to the 10 batteries, four batteries are aligned in the direction of the axis Y, and they are stacked in three tiers, i.e., an upper tier, a middle tier, and a lower tier. Each non-illustrated spacer is provided between thebatteries 2 in the upper tier and thebatteries 2 in the middle tier and between thebatteries 2 in the middle tier and thebatteries 2 in the lower tier. That is, each spacer is provided between the respective tiers. - The
battery box 3 is a box accommodating thebatteries 2, and other parts. Thebattery box 3 has a substantially rectangular parallelepiped shape. - The battery apparatus 1 has a space corresponding to two
batteries 2 formed in the upper tier of the stackedbatteries 2 in thebattery box 3. Although not shown, for example, an electronic circuit such as a control circuit that controls the battery apparatus 1 is accommodated in this space. - The
heat equalizing plate 10 is disposed to come into contact with all the 10batteries 2. Specifically, theheat equalizing plate 10 is arranged to come into contact with bottom surfaces of all thebatteries 2 in thebattery box 3. Here, the bottom surface of thebattery 2 is a surface that has the same orientation as the axis X in the state of thebattery 2 depicted inFIG. 1 . - In this embodiment, the following functions and effects can be obtained.
- The
battery 2 generates heat when energized. At this time, a temperature of thebattery 2 fluctuates depending on the position where thebattery 2 is located. - Thus, the
heat equalizing plate 10, which has an excellent thermal conduction property, is arranged to come into contact with all thebatteries 2 in the battery apparatus 1. As a result, fluctuations in temperature between eachbattery 2 can be reduced. - Therefore, the battery apparatus 1 can be a battery apparatus suitable for use in an electric light vehicle.
-
FIG. 2 is a structural view showing a structure of abattery apparatus 1A according to a second embodiment of the present invention. Thebattery apparatus 1A has aheat equalizing plate 10A provided in place of theheat equalizing plate 10 in the battery apparatus 1 according to the first embodiment depicted inFIG. 1 . Other points are the same as for the battery apparatus 1. - The
heat equalizing plate 10A is disposed to come into contact with allbatteries 2 placed in the lowermost tier. Specifically, theheat equalizing plate 10A is arranged to come into contact with lower surfaces of fourbatteries 2 placed in the lowermost tier. - According to this embodiment, the following functions and effects can be obtained.
- The
battery apparatus 1A mounted in an electric light vehicle receives an air stream from the arrow direction of the axis Y when the electric light vehicle travels. As a result, eachbattery 2 disposed in the arrow direction (a front wheel side) of the axis Y of thebattery apparatus 1A is apt to be cooled. On the other hand, cooling of eachbattery 2 disposed on an opposite side (a rear wheel side) of the arrow direction of the axis Y of thebattery apparatus 1A is difficult. Therefore, thebatteries 2 have unevenness in temperature depending on their location in the direction of the axis Y of the battery apparatus 1. - Thus, the
heat equalizing plate 10A is disposed in thebattery apparatus 1A to come into contact with all thebatteries 2 placed in the lowermost tier. As a result, it is possible to suppress unevenness in temperature of thebatteries 2 due to their location in the direction of the axis Y of the battery apparatus 1. -

battery apparatus 1C has aheat equalizing plate 10C provided in place of theheat equalizing plate 10 in the battery apparatus 1 according to the first embodiment depicted inFIG. 1 . Other points are the same as for the battery apparatus 1. - The
heat equalizing plate 10C has a shape obtained by disposing aplanar portion 101C to theheat equalizing plate 10, theplanar portion 101C being vertical to theheat equalizing plate 10. Therefore, theheat equalizing plate 10C has a T-like shape. It is to be noted that theheat equalizing plate 10C may have an L-like shape by disposing theplanar portion 101C to a portion corresponding to an end portion of theheat equalizing plate 10. Theplanar portion 101C of theheat equalizing plate 10C protrudes toward the outside from an opening portion provided in abattery box 3. - According to this embodiment, it is possible to obtain the following functions and effects in addition to the functions and effects according to the first embodiment.
-

battery apparatus 1D has aheat equalizing plate 10D provided in place of theheat equalizing plate 10A in thebattery apparatus 1A according to the second embodiment depicted inFIG. 2 . Other points are the same as for thebattery apparatus 1A. - The
heat equalizing plate 10D has a shape obtained by disposing aplanar portion 101D to theheat equalizing plate 10A depicted inFIG. 2 , theplanar portion 101D being vertical to theheat equalizing plate 10A. Therefore, theheat equalizing plate 10D has a T-like shape. It is to be noted that theheat equalizing plate 10D may have an L-like shape by disposing theplanar portion 101D to a portion corresponding to an end portion of theheat equalizing plate 10A. Theplanar portion 101D of theheat equalizing plate 10D protrudes toward the outside from an opening portion provided in abattery box 3. - According to this embodiment, it is possible to obtain the following functions and effects in addition to the functions and effects according to the second embodiment.
-
Batteries 2 in thebattery apparatus 1D can be directly cooled by outside air by protruding theplanar portion 101D of theheat equalizing plate 10D toward the outside of thebattery box 3. Therefore, theplanar portion 101D functions as a radiator plate, thereby effectively suppressing an increase in temperature of thebatteries 2. -
FIG. 6 is a structural view showing a structure of abattery apparatus 1E according to a sixth embodiment of the present invention. - The
battery apparatus 1E has aheat equalizing plate 10E provided in place of theheat equalizing plate 10 in the battery apparatus 1 according to the first embodiment depicted inFIG. 1 . Other points are the same as in the battery apparatus 1. - The

Therefore, theheat equalizing plate 10E has a shape formed in one plane. Theheat equalizing plate 10E has a shape including aplanar portion 101E protruding toward the outside from an opening portion provided in abattery box 3. - According to this embodiment, it is possible to obtain the following functions and effects in addition to the functions and effects according to the first embodiment.
-
Batteries 2 in thebattery apparatus 1E can be directly cooled by outside air by protruding theplanar portion 101E of theheat equalizing plate 10E toward the outside of thebattery box 3. Therefore, theplanar portion 101E functions as a radiator plate, thereby effectively suppressing an increase in temperature of thebatteries 2. - Further, the
heat equalizing plate 10E has a shape based on one plane, thus reducing a manufacturing cost in, e.g., processing. -
FIG. 7 is a structural view showing a structure of abattery apparatus 1F according to a seventh embodiment of the present invention. - The
battery apparatus 1F has aheat insulating material 12 additionally provided in the battery apparatus 1 according to the first embodiment depicted inFIG. 1 . Other points are the same as in the battery apparatus 1. - The
heat insulating material 12 is provided between batteries placed in the uppermost tier and an upper surface of abattery box 3. Theheat insulating material 12 covers upper surfaces of all thestacked batteries 2. Theheat insulating material 12 plays a role of inhibiting thermal conduction properties from the upper surface of thebattery box 3 to thebatteries 2. - According to this embodiment, it is possible to obtain the following functions and effects in addition to the functions and effects according to the first embodiment.
- The upper surface of the
battery apparatus 1F may be directly exposed to the sunlight in a state where thebattery apparatus 1F is mounted in an electric light vehicle.
